G-UN-SIGHTI-NG APPARATUS.

SPEGIFICATION forming part of Letters Patent N 0. 687,324, dated November 26, 1901- Application filed April 9, 1901.

To all whom it may concern.-

Be it known that I, EDWARD WILLIAM LLOYD, latecommander Royal Navy, a subject of the King of GreatBritain, residing at Elswick Works, Newcastle-upon-Tyne, England, have invented a certain new and useful Gun-SightingApparatus for Practice Pur poses,of which the following is a specification.

The object of this invention is to provide a moving target at which gunners may practice the aiming of ordnance Without actual firing thereof and also a means of recording the alinement of the gun at the instant when the trigger is pulled. i

The apparatus consists of a miniature target placed a short distance in front of the gun and capable of being moved in any di rection by hand and a paper or diagram holder which moves with the target and which is marked at the moment the electric circuit of the gun-firing mechanism is closed by a pencil or the like fixed to and moving with the gun.

Figure l is a side elevation, Fig. 2 a front elevation, and Fig. 3 a section on the line 3 3, Fig. 2, of an apparatus constructed according to this invention. Fig.4 is a plan, and Fig. 5 a side elevation, showing in diagram the manner in which the apparatus is connected to the gun.

The target a consists of a plate mounted on abar b, along which it can slide for horizontal movement, while the bar can slide up and down in the frame 0. The horizontal movement is given by a cord (1, fixed at a to the target, which moves it against a spring 6, so that when the cord is let go the target is pulled back by this spring. Pulleys f may be employed, as shown, for the purpose of reducing the extension of the spring 6.

The target is operated vertically by means of endless chains g, connected at g to the bar I) and driven by ahandle h. The speed in this case also may be reduced by gearing, as shown.

The marking mechanism consists of an electromagnet in circuit with. the firing-pistol 0 or other firing mechanism of the gun, so that when the operator chooses to fire electric connection is made and the magnet attracts its Serial No. 55,062. (No model.)

armature j, forcing a pencil or other marker 70, carried by the lever Z, pivoted at Z, forward against a sheet of paper moving with the target, thus recording the direction of the gun when it was fired. In the arrangement shown the target a. itself forms the diagramcarrier; but they may be separate so long as they move together. It is indeed preferable that the diagram and pencil should be out of sight of the gunner. Im mediately after firing the armature j is liberated and a springj brings it back into its normal position. The magnet j is mounted on a, slide 0%, free-to move horizontally along the bar n, which itself can move up and down in the frame 0.

m represents lugs on the slide m, by which it can be secured to the muzzle of the gun.

This is done by means of a plug or tampion fined two forks r to receive the lugs m.

To avoid confusion, the parts are shown in Figs. 1 to 3 of the drawings in a position corresponding to a bad aim, and if the trigger were pulled when the parts were in this p0- sition the gunner would score a miss, for no mark would be made on the target a, because the pencil is not then in reach of it. When, however, the trigger is pulled at the proper time to score a hit, the pencil will make a mark' on the target-that is to say, when the parts are inthe position shown in Figs. 4 and 5.

What I claim is 1. The combination of a target, means for moving the same, a marker, means for connecting the marker to the gun, and an electromagnet operating the marker.

2. The combination of a target, means for moving the target in a horizontal direction, means for moving the target in a vertical direction, a marker, means for connecting the marker to the gun, and an electromagnet operating the marker.

3. The combination of a frame, a bar free to slide vertically in the frame, an endless chain fixed to the bar, a chain-wheel operat ing the chain, a target free to slide along the bar, a spring tending to draw the target in one direction along the bar, a cord fixed to the target and by which it can be drawn in the other direction, a marker, means for operating the marker, and means for connecting the marker to the gun.

4. The combination of a frame, a bar free to slide vertically in the frame, an endless chain fixed to the bar, a chain-wheel operating the chain, a target free to slide along the bar, a second her free to slide vertically in the frame, a slide free to move along the sec- 10 0nd bar, means for connecting the slide to the gun, a marker carried by the slide and an electromagnet carried -by the slide and operating the marker.
